Well buying a expensive phone and soon after u see the phone occuring problems, that is just not so good, My HTC Desire Hd had a speaker sound problem, which I thought that the speakers are broken, cause it sounded like that, I could have hear the sound for had second and dissapears, and when I was turning the loudspeakers on or headphones, everything was normal... SO I CALLED HTC CUSTOMER SERVICE, FInd the phone number in internet where you live! They told me to GO SETTING > SD PHONE STORAGE> the last option, delete all programms. REMEMBER that all ur contacts and messages or downloaded files and picture would be deleted so keep them at ur memory card or contacts in SIM memory! and get started will take few moments, and ur phone will be restarted soon.. Maybe after restart the speaker will sound the same but give it few moments.
